Embodiment 1
[0045] The selected peritectic steels with cross-sectional dimensions of 2100mm×250mm, 1600mm×300mm and 2300mm×180mm respectively, the target composition contains C0.17%, Si0.15%, Mn0.60%, P≤0.015% by weight percentage, S≤0.015%, the balance is Fe; casting temperature is 1545°C, casting speed is 0.9~1.1m / min;
[0046] A two-dimensional solidification heat transfer calculation model is established. The heat transfer of the slab in the secondary cooling zone is mainly composed of radiation, roller contact heat transfer and secondary cooling convective heat transfer. The convective heat transfer coefficient of the secondary cooling water is The calculation method of can be expressed as:
[0047] h w i = α i · W i ( x ) 0.55 · ( ...
